After attempting to modify the initIframe() function in the "HTMLArea.prototype.generate" prototype, I've noticed that when the content is written to the iFrame, it essesntially creates a browser history item.

The problem this creates is that if a user that wants to go to the previous page (by hitting "Back" in their browser) they must click "Back" twice. The first click unloads the WYSIWYG data; the second returns to the previous URL.
